摘要： Circuit for modulating a crystal oscillator, having an overtone crystal, wherein a self-inductance (L1) and a parallel circuit comprising a capacitor (C3) and a diode (D2) in series with a predetermined reference voltage (Uref) are connected in series with the crystal element (X), such that a modulation voltage connected to the junction of the self-inductance (L1) and the parallel circuit including the capacitor (C3) and the diode (D2) results in a large frequency deviation of the oscillator; the diode (D2) is preferably a pin diode.

摘要： The invention relates to a method for taking a soil sample. A flexible cover is fitted around a cutting head of a sampling device before the sampling device is introduced into a borehole. When a sample is being taken, the flexible cover is pierced and soil, for example, can enter the cutting head. The cutting head is thereby prevented from being contaminated with material from the walls of the borehole. The invention also relates to a sampling device provided with a flexible non-return valve, for example in the form of a pointed pouch, which is partly connected to the inner wall of the hollow cutting head of the sampling device, and to a tube for use in such a sampling device.

摘要： Transponder provided with: a receiving circuit for receiving interrogation signals and electromagnetic field energy, energy storage means for storing the received electromagnetic field energy and for delivering power to the transponder, interrogation signal processing means for detecting the interrrogation signal, a measuring circuit coupled to one or more sensors for measuring the value of one or more external ambient parameters, and a transmitting circuit which, after reception of an interrogation signal, transmits the parameter value(s) measured by the measuring circuit. The transponder is furthermore provided with a time-determining circuit which activates the measuring circuit at predetermined times to carry out one or more measurements of the said ambient parameter(s). The measuring circuit is provided with a memory in which a number of measured parameter values can be stored. The energy storage means have sufficient capacity to supply power within a predetermined period to the time-determining circuit in order to keep it in operation during said period and also to supply power to the measuring circuit if it is activated within said period by the time-determining circuit.

摘要： The invention relates to a method and apparatus for determining a material composition such as the presence of contamination in a soil stratum. By measuring the impedance of the material at various positions such as depths x and x + DELTA x, or times x + DELTA x, determining the conductivity G and the capacitance C from the measured impedances and determining the ratio of the derivatives of the conductivity and the capacitance with respect to time, it is possible to use the ratio of dG(x) and dC(x) as an indicator for the material composition. It is found, surprisingly, that when the presence of contamination in a soil is determined, this ratio is mainly determined by a natural composition of the soil and does not vary greatly for a relatively small distance. Unnatural changes in the ratio dG(x)/dC(x) are therefore an indication for the presence of certain substances such as contaminants.
摘要翻译：本发明涉及一种用于确定材料成分如土层中污染物的存在的方法和装置。通过测量材料在诸如深度x和x + DELTA x或x + DELTA x的各种位置处的阻抗，根据测量的阻抗确定电导率G和电容C，并确定电导率的导数和相对于时间的电容，可以使用dG（x）和dC（x）的比率作为材料组成的指标。令人惊讶地发现，当确定土壤中污染物的存在时，该比例主要由土壤的天然组成决定，并且在相对小的距离内不会有很大变化。因此，比例dG（x）/ dC（x）的非自然变化是某些物质如污染物的存在的指示。
